Chiral oxazolines, as their boron enolates derived from various boron triflates, react with aldehydes to give erythro-selectivity (97% + %) with enantiomeric purities of 50–60%. Achiral oxazolines as their boron enolates derived from diisopinocampheylborane give, on reaction with aldehydes, β-hydroxy esters with high threo-selectivity (90+%) in 77–85% ee. A variety of structurally different oxazolines
手性恶唑啉是源自三氟甲磺酸三氟硼烷的硼烯酸酯,它与醛反应生成对映异构体纯度为50-60%的赤型选择性(97%+%)。非手性恶唑啉作为二异硫代樟脑硼烷的硼烯酸酯,与醛反应后,在77–85%ee中具有高苏式选择性(90%以上)的β-羟基酯。还研究了各种结构不同的恶唑啉,其中许多显示出高的赤型选择性。
